[TYPO3] Developing own extensions

[Heiner Lamprecht]

Hi everybody,

I'm playing a little bit with developing own extensions but still 
have some problems in understanding the way T3 works.

I'd like to change the way an image link is created.  At the moment, 
it's a long link, including the path of the imagefile.  As I'm 
using DAM incl. dam_ttcontent, it would be sufficient to add only 
the ID of the content-element and of the image.

The idea behind is, that with those two IDs, I would be able to 
display not only the image itself, but also a thumbnail of the 
previous and the next image, if the content element contains more 
than one image.

My problem is, that I don't see where I can get the ID of the 
content element.  I would like to have some kind of a stack trace 
to see, which functions are called in order to generate the 
HTML-output for the content.  But I don't really understand the way 
PHP and TypoScript work together here.

Does anybody have some hint?


Thanks and best regards,


    Heiner
